This is a list of Frequently Asked Questions (and answers) for the
area of constraints, including books, journal articles, ftp archives,
and systems & products. It is posted once a month to the newsgroups
comp.constraints, comp.answers, and news.answers.

NOTE: the Constraints Archive web pages contain far more information
than the FAQ, including pointers to other web pages and ftp sites:
http://www.cirl.uoregon.edu/constraints/

This guide is regularly posted in two parts to comp.constraints. It
may also be obtained from the WWW pages, and from the archive on
rtfm.mit.edu in the directory /pub/usenet/news.answers/constraints-faq.
You can also access the rtfm archive by mail server as well. Send an
e-mail message to mail-...@rtfm.mit.edu with "help" and "index"
in the body on separate lines for more information.

Subject: [1-2] Other related FAQs

Many FAQs are posted to the news.answers newsgroup, and, if
appropriate, to comp.answers and other groups. These FAQs are archived
at <ftp://rtfm.mit.edu/pub/usenet/>. For example, the comp.constraints
FAQs are in the <ftp://rtfm.mit.edu/pub/usenet/comp.constraints/>
directory.

These FAQs are also automatically converted to HTML (in most cases,
this just means that URLs are converted to hot links), and archived in
various places such as the News.Answers Faqs Archive
<http://www.cs.ruu.nl/cgi-bin/faqwais> at Utrecht; for example, the
comp.constraints FAQ
<http://www.cs.ruu.nl/wais/html/na-bng/comp.constraints.html>,
converted to HTML format, can be found there. You can also search the
collection of FAQs. Also see Smartpages

maintained by Tom Fine, Infoseek <http://guide.infoseek.com/> (one of
the search options is "Usenet FAQs"), and Kent Landfield's archive

The sci.op-research newsgroup has FAQs for linear and non-linear
programming <http://www.mcs.anl.gov/home/otc/Guide/faq/> These can be
found in ascii format, along with an index of resources for numerical

and logic programming. It is specially concerned with the integration
of the functional and logic paradigm as well as their common
foundations. The Journal expects articles ranging from the theoretical
foundations of functional and logic programming up to the application
of such languages in the real world. The Journal is published by The
MIT Press. See <http://mitpress.mit.edu/jrnls-catalog/jflp.html> or

Subject: [1-10] Constraint libraries for Lisp and C

Patrick Prosser <p...@cs.strath.ac.uk> discusses various standard
algorithms in the journal Computational Intelligence vol 9(3), 1993.
Scheme versions available from Pat on request; Lisp implementations are
available from <ftp://ftp.cs.strath.ac.uk/local/pat/csp-lab>.

Peter Van Beek <van...@cs.ualberta.ca> has written a set of libraries
for C. This package is available from

also csplib.tar.Z.

Screamer
<http://www.cirl.uoregon.edu/constraints/systems/screamer.html> is a
constraint library for Common Lisp.

Michel Lemaitre has written a Common Lisp library dedicated to the
resolution of "Valued Constraint Satisfaction Problems" (for a
description of VCSP, see
<ftp://ftp.cert.fr/pub/verfaillie/ijcai95.ps>). The library has been
designed with efficiency in mind. It includes Branch and Bound
extensions of the Backtrack and Forward checking algorithm as well as
the "Russian Doll Search" algorithm described in
<ftp://ftp.cert.fr/pub/verfaillie/rds-aaai96.ps>, and several benchmark
problems. The library is available at
<ftp://ftp.cert.fr/pub/lemaitre/LVCSP/>.

The Enterprise Integration Laboratory at the University of Toronto is
seeking a research scientist for a 1-year contract (with strong
possibility of renewal) working in the Intelligent Scheduling Research
Group (ISRG). ISRG is a joint project of the Enterprise Integration
Laboratory and Numetrix, Ltd., a leader in the supply chain management
software industry.

The focus of the group is the exploration and application of
constraint-directed scheduling technologies to industrial scheduling,
distribution, and supply chain coordination problems. We have
developed, NumODO, a constraint-directed scheduler with the ability to
emulate a variety of state-of-the-art scheduling algorithms. NumODO
combines generative scheduling and iterative improvement under the
unifying concepts of constraints, textures, and heuristic and implied
commitments and allows direct comparison of competing techniques.
